Sunlight shines directly into the phenomenon of body surface, is called sunshine.The phenomenon that sunlight shines directly into building location, architecture enclosing body structure surface and house interior is called building sunshine.Building sunshine mainly is that the research beam radia is to the effect of buildings and the requirement of buildings counterglow.
Because solar radiation causes vegeto-animal various photobiology reaction, thereby promote the metabolism of living organism.Contained ultraviolet ray can prevent and treat some diseases in the sunlight, as flu, bronchitis, tonsillitis and rickets etc.Therefore, buildings has important health meaning is arranged suitable sunshine; Secondly, contain a large amount of infrared rays and visible light in the sunlight, indoor if energy direct projection in winter is gone into, the thermal effect that is produced can improve indoor temperature, and good heating and desiccation are arranged, and is more favourable to the north of the Yangtze river basin.
Therefore building sunshine is the key factor that must consider in urban and rural planning and the architectural design, and along with the development of urbanization process and construction business, the people raising to environmental quality requirement, its meaning will be more extensive and far-reaching.So, the length of estimating the building sunshine time is used the sunshine time.To entering horizontal line occidentally, its direct projection light shines the time that ground experiences under any conditions of covering such as no atural object, cloud, mist, be called " sunshine time " from the horizontal line eastwards that appears at a ground at sun center.The sun is called " sunshine time " at the time number on a local actual irradiation ground.Sunshine time is hour to be unit, and available sunshine recorder is measured.Sunshine time is a percentage of sunshine with the ratio of sunshine time, and it can weigh the illumination condition in an area.
The instrument of measuring sunshine time mainly contains three kinds, they are dark-tube sunshine recorder, focusing sunshine recorder, photoelectricity sunshine recorder, surveying instrument all was not suitable for the sunshine time and measured at sunshine these, more be not suitable for actual sunshine time measurement, according to the retrieval, the instrument of measuring the sunshine time does not still have at present, and research and development are used to measure the method and apparatus of building actual sunshine time quantitative measurment and seem especially urgent and necessary.
Summary of the invention
Purpose of the present invention provides a kind of quantitative quick measuring method for shining time per year based on position of sun emulation, solve the length problem of building sunshine time of how measuring, for building sunshine designs, dispute and house quality evaluation at sunshine that the building shade causes propose a quantitative foundation.
The present invention is achieved like this, its measurement mechanism is made up of 6 parts, the mapping support, be installed in the polar coordinates servo positioning The Cloud Terrace of mapping on the support, be installed in laser range finder, controller, portable computer, portable printer on the polar coordinates servo positioning The Cloud Terrace spiral arm, measuring method is the time period that earlier certain date is fallen from the The sun came up to the sun to carry out moment sampling according to certain time interval (for example 5 minutes), utilizes the portable computer sampling instant.The time period that certain date is fallen from the The sun came up to the sun is carried out moment sampling according to certain time interval (for example 5 minutes), utilize portable computer the calculating sampling elevation angle and the position angle of the sun constantly, and the drive signal that this elevation angle and position angle is converted to stepper motor is sent controller, thereby by controller drives polar coordinates servo positioning The Cloud Terrace, make the laser range finder that is installed on the automatic positioning cradle head spiral arm can in time point to the position of this sampling instant sun, find range if start laser range finder by controller this moment, if can measure barrier (does not promptly overflow, can inquire about by communication software), illustrate that sunlight is blocked, sunlight should can not be enjoyed in this moment on date in the laser range finder present position; If the range finding outrange illustrates that then sunlight is not blocked, sunlight should can be enjoyed in this moment on date in the laser range finder present position.
Advantage of the present invention is: utilize this method to measure the actual sunshine time in year that has house or building now by fast quantification, and can round-the-clockly measure, because calculate according to the natural law at the elevation angle of the sun and position angle in this measuring method, avoided measuring sunshine the actual measurement condition that need see sunlight in the past, therefore this measuring method can be at any time, carry out under any weather condition, even cloudy day, night also can be surveyed the actual sunshine time.
